Product views and applications

ExMax-...-F1 Safety damper
Description
The ExMax actuators are a revolution for safety, control and shut-off
dampers and other motorized applications for HVAC systems in chemical,
pharmaceutical, industrial and offshore/onshore plants, for use in Ex-areas
zone 1, 2 (gas) and zone 21, 22 (dust).
Highest protection class (ATEX) and IP66 protection, small dimensions,
only 3,5 kg weight, universal functions and technical data, an integrated
heater and an optional stainless steel housing guarantee safe operation
even under difficult environmental conditions. High quality brushless
motors guarantee long life.
All actuators are programmable and adjustable on site. Special tools or
equipment are not required. Motor running times are selectable on site.
The integrated universal power supply is self adaptable to input voltages
in the range of 24...240 VAC/DC. The actuators are 100% overload
protected and self locking.
...Max-...-F1 actuators are equipped with spring return fail safe function.
Additionally the ...Max-...-SF1 and ...-BF1 actuators are equipped with
2 integrated, potential free auxiliary switches each and ...Max-...-BF1
comes with an intrinsically safe tripping circuit for connecting the ...Pro-TT-...
safety temperature trigger. Standard shaft connection is a double square
direct coupling with 12 × 12 mm.
Different accessories are available to adapt auxiliary switches, terminal
boxes or adaptions for ball valves and throttle valves and other armatures.
